CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application No. 61/860,482, filed Jul. 31, 2013.

FIELD OF THE INVENTION

The present disclosure relates to a surgical instrument, and, more particularly, to a laser probe with a replaceable optic fiber.

BACKGROUND OF THE INVENTION

A wide variety of ophthalmic procedures require a laser energy source. For example, ophthalmic surgeons may use laser photocoagulation to treat proliferative retinopathy. Proliferative retinopathy is a condition characterized by the development of abnormal blood vessels in the retina that grow into the vitreous humor. Ophthalmic surgeons may treat this condition by energizing a laser to cauterize portions of the retina to prevent the abnormal blood vessels from growing and hemorrhaging. Typically, treatments are performed using a disposable, single-use laser probe connected to a laser surgical machine by an optical fiber. Unfortunately, use of disposable, single-use laser probes increases treatment costs because a new laser probe is required for each surgical treatment. Accordingly, there is a need for a laser probe that may be safely used to perform more than one surgical procedure.

BRIEF SUMMARY OF THE INVENTION

In one or more embodiments, a laser probe with a replaceable optic fiber may comprise a reusable handle having a handle distal end and a handle proximal end, a reusable housing tube having a housing tube distal end and a housing tube proximal end, a reusable handle adapter having a handle adapter distal end and a handle adapter proximal end, a reusable machine adapter having a machine adapter distal end and a machine adapter proximal end, and a replaceable optic fiber. Illustratively, the handle adapter may be configured to interface with the handle proximal end. In one or more embodiments, the machine adapter may be configured to interface with a surgical machine. Illustratively, the replaceable optic fiber may comprise an optic fiber having a first optic fiber end and a second optic fiber end, a first connector having a first connector distal end and a first connector proximal end, and a second connector having a second connector distal end and a second connector proximal end. In one or more embodiments, the optic fiber may be disposed within the first connector and the second connector wherein the first optic fiber end extends a distance from the first connector distal end and the second optic fiber end extends a distance from the second connector distal end. Illustratively, the first connector may be temporarily fixed within the handle adapter and the second connector may be temporarily fixed within the machine adapter.
